Define "terminated abnormally". You really aren't going to get helpful
answers without giving full details of what happened. (If the
postmaster thought the backend had crashed, it would have forced a
database restart which would have wiped shared memory. So it's not
clear from your comment what did happen.)
Also, exactly which PG version is this?
